Abstract (en)

[origin: WO2020160597A1] A dual battery system, including: a primary battery which drives a starter motor; an auxiliary battery which drives one or more auxiliary loads; an alternator which supplies current to recharge the primary battery; and a power supply circuit which supplies current from the alternator to recharge the auxiliary battery when a surplus condition is detected, the surplus condition indicating that the alternator is generating more electrical power than is required for recharging the primary battery, wherein the power supply circuit ceases to supply current to recharge the auxiliary battery when absence of the surplus condition is detected so that the primary and auxiliary batteries become electrically isolated, thereby ensuring that recharging of the auxiliary battery does not have an adverse effect on the level of charge of the primary battery.
